2 FOREWORD (DNV) is an autonomous and independent foundation with the objectives of safeguarding life, property and the environment, at sea and onshore. DNV undertakes classification, certification, and other verification and consultancy services relating to quality of ships, offshore units and installations, and onshore industries worldwide, and carries out research in relation to these functions. Standards for Certification Standards for Certification (previously Certification Notes) are publications that contain principles, acceptance criteria and practical information related to the Society's consideration of objects, personnel, organisations, services and operations. Standards for Certification also apply as the basis for the issue of certificates and/or declarations that may not necessarily be related to classification. A list of Standards for Certification is found in the latest edition of Pt.0 Ch.1 of the Rules for Classification of Ships and the Rules for Classification of High Speed, Light Craft and Naval Surface Craft. The list of Standards for Certification is also included in the current Classification Services Publications issued by the Society, which is available on request. All publications may be ordered from the Society s Web site The Society reserves the exclusive right to interpret, decide equivalence or make exemptions to this Standard for Certification. Comments may be sent by to rules@dnv.com Comprehensive information about DNV and the Society's services is found at the Web site Det Norske Veritas Computer Typesetting (FM+SGML) by Det Norske Veritas If any person suffers loss or damage which is proved to have been caused by any negligent act or omission of Det Norske Veritas, then Det Norske Veritas shall pay compensation to such person for his proved direct loss or damage.

4 4 Standard for Certification - No. 2.20

5 Standard for Certification - No Introduction to Users 1.1 General Format and editorial details of the Standard are described in the following to facilitate easy use. This Standard for Certification of Lifeboats and Rescue Boats replace previously issued Certification of Lifeboats (1998). The requirements are established by the Society on the basis of service experience and safety records of representative boat types, size and building materials. The certification systems described in this Standard are somewhat different compared with other classification rules issued by the Society, as this Standard is harmonised with the Marine Equipment Directive. This Standard is applicable if the size, building material and service of the boats are in compliance with the given limitations. 1.2 How to use the standard The contents of the Standard are such that: Sections 1 through 4 - cover introduction Sections 5 through 10 - cover certification system and general technical requirements Sections 11 through 13 - cover specific requirements depending on type of craft. 2. The Standard 2.1 Applicability This Standard applies to all newbuilding for which application for type approval is received after This Standard applies to all existing type approved lifeboats from the date of renewal of the DNV Type Approval Certificate or EC Type Examination Certificate. 2.2 Format The first paragraph in each chapter/section will normally be termed General Requirements and will contain subsections covering such aspects as application of the Standard, definitions of symbols and terms, list of documentation etc. 2.3 Numbering and cross references To identify a specific paragraph it is necessary to give the specific chapter/section, together with the paragraph, i.e first paragraph would identify this paragraph. Figures are numbered in increasing order within each chapter/ section, e.g. Fig.2-1, Fig.2-2 etc. Tables are numbered in increasing order within each chapter/ section, e.g. Table 2-1, Table 2-2 etc. 2.4 Index and tables of contents A table of contents is given at the beginning of the document, providing the pages for each section/chapter. 2.5 Amendments Amendment of existing technical requirements is the result of formal proposals from the technical staff of the Society, based on practical in service experience as well as comprehensive theoretical studies, research and development. Such proposals are commonly discussed with representatives of builders, owners, maritime governmental bodies and insurance company associations, before being adopted. Amendments may be undertaken at any time, issued normally twice a year and made known by highlighting the changes on the inside cover of the most recent issue. 2.6 Reprints Reprints from the Standard are available from the Society on request. There is currently no subscription scheme for reprints. While the Society will publish details of amendments to the Standard in its own magazines, no special notification of amendments to buyers of reprints will be undertaken. 3. Guidelines, Registers and Lists 3.1 General Products which shall be approved may be granted Type Approval. The Society has issued Registers of Approved Manufacturers and Type Approved Products containing the names of manufacturers and types of products which have been granted approval. The approval is time limited and updated registers are normally published annually. 3.2 Registers of Approved Manufacturers and Type Approved Products Register of Approved Manufacturers and Type Approved Products can be found in DNV homepage 4. Preamble to the Standard 4.1 Introduction This preamble explains the system of certification, how it works, conditions of validity, and its interaction with statutory control. This information is to a large extent implied by the Standard, but a brief clarification of the essential points in one place is considered useful. This information is not in any way to be understood as a requirement. For a better understanding of DNV s modus of operation, systematics, remuneration and support, reference is also given to DNV Rules for Classification of Ships Pt.0 Ch.2 and Pt.1 Ch General certification Certification is used within the classification system to verify conformity with requirements in the design and construction phase, by application of one or a combination of specified certification modules. The DNV Type Approval Certification system for Boats is based on the EU Module Certification system. When the client has applied for certification of the lifeboat according to the Marine Equipment Directive, the Society will fully apply the procedures in the Marine Equipment Directive. The technical requirements in the chapter/ section named: Technical requirements will apply as the Society s understanding of the LSA Code. 4.3 The Standard and in service experience The Standard is developed and published by the Society, even when based on and covering mandatory regulations as IMO Conventions or EU Directives. In addition to technical requirements, documentation requirements and certification procedures are also given. The Society will revise the Standard on the basis of available experience feedback from service, and will apply additional requirements if found necessary.

6 6 Standard for Certification - No The Certification System 5.1 Obligations Certification according to this Standard and the Marine Equipment Directive are aimed at safeguarding life and property at sea and the environment, as a consequence of operation of vessels. It implies a process of verifying standards against a set of requirements established by the Society. Certification is not performed as a substitute for the client s own quality and safety control and related duties, nor the client s obligations towards third parties, nor to relieve any consequences of default. The Society keeps complete files on all boats covering the documentation required by the Standard. Reports will not be disclosed to any party, apart from the National Authorities involved, without the owner's consent. The Society also undertakes all reporting to National Authorities required, in connection with the safety certificates. 5.2 Who needs certificates? Certificates serve as a verification system for a number of parties who have special interest in the safety and quality of ships, vessels and boats, such as: National Authorities, who need assurance that vessels are safe to use and represent a minimum hazard to their surroundings. Insurance underwriters, who need to know the standard of the vessel in order to assess the insurance fee for the vessel. Owners, who need the technical standard as basis for building contracts and to document the standard when seeking insurance or financing, or when hiring out or selling the vessel. Building yards and sub-contractors, who use the Standard as a tool for design and construction, as required by their client, to avoid technical barriers to trade and to obtain access to markets which require certificates. Manufacturers, who use certification as a part of their documentation when they place their products on the market. Finance institutions, which use the classification standard as a documented indicator of the maintenance and value of the vessel in service. Charterers or cargo owners, who require confirmation of the standard before hire. 5.3 Certification of newbuildings The builder initiates the process by submitting a request for certification to the Society. In response to a list of documentation issued by the Society, the builder and sub-suppliers submit plans, specifications, related technical descriptions and data, including specification of materials, as required by the Standard for approval. After examining the above documents, the Society informs the builder whether the design and arrangement of structure, machinery and equipment is acceptable. If not, the Society may propose modifications needed to meet the requirements. During the building period the Society carries out surveys at the building yard. The method and extent of survey will be decided by the Society based on the acceptance of their quality system and the certification system to be applied. The purpose of the surveys shall verify that the construction, components and equipment satisfy the Standard requirements and are in accordance with the approved plans, that required materials are used, and that functional tests are carried out as prescribed by the Standard. When the boat is completed and the Society is satisfied that the requirements specified for the boat in question have been met, confirmed by the issuance of certificates and a boat marking plate. 6. Type Approval and Type Examination 6.1 General The DNV Standard for Certification No.1.2 as amended applies as basis for Type Approval. The Society is the certification body. Type Approvals will be listed and published on DNV website. 6.2 Request Requests for Type Approval shall be submitted by the manufacturer or his authorized representative to the Society. The request shall include: the name and address of the manufacturer and, if the request is lodged by the authorized representative, his name and address, in addition: the extent of approval (i.e. cargo/tanker version) the technical documentation as specified by the Society. 6.3 Documentation To ensure that the technical documentation is in compliance with the requirements, approval of the documentation is required before issuance of the certificate. 6.4 Examination and testing To verify that the type has been manufactured in conformity with the Standard, survey of the type shall be carried out prior to issuing certificate. 6.5 Certificate Where the type meets the provisions of the Standard, the Society shall issue a Type Approval or a Type Examination certificate to the applicant. The certificate shall contain the name and address of the manufacturer, conclusions of the examination, and conditions for its validity and the necessary data for identification of the approved type. A list of the relevant parts of the technical documentation shall be annexed to the certificate and a copy kept by the Society. If the manufacturer is denied a Type Approval or a Type Examination certification, the Society will provide detailed reasons for such denial. The applicant shall inform the Society of all modifications to the approved product. This additional approval is given in the form of an addition to the original Type Approval certificate. 7. Product Certification 7.1 General It is a condition that the product is Type Approved or Type Examined to obtain a Product Certificate. The Society is the certification body. 7.2 Scope This module describes the procedure whereby a manufacturer or his authorized representative checks and attests that the products subject to the provisions of this paragraph are in conformity with the type as described in the Type Approval or Type Examination certificate and satisfy the requirements of the Standard that apply to them. The manufacturer shall make sure that the manufacturing process ensures conformity of the products with the type as described in the Type Approval or Type Examination certificate and with the requirements that apply to them. The Society will carry out the examinations and tests in order to check the conformity of the product with the requirements

7 Standard for Certification - No of the Standard by examination and testing of every product. Based on compliance with the above two latter conditions, the manufacturer shall affix the certification signboard to each product. 7.3 Survey All products shall be individually examined and tested as set out in the relevant Standard, or equivalent tests shall be carried out in order to verify their conformity with the type as described in the Type Approval or Type Examination certificate and the requirements of the Standard that apply to them. The manufacturer shall keep a record of all complaints and remedial actions relative to the products for a minimum of 10 years. 7.4 Product Certificate A Product Certificate is issued for the vessel on the basis of the Type Approval or Type Examination Certificate and the surveys of the product under Type Certification Procedure for Lifeboats Table 8-1 Type Certification Process for Lifeboats Phase 1 Approval Phase 2 Construction of prototype Phase 3 Testing of prototype 9.

To obtain proper air circulation the forward ventilation opening shall supply air as low as possible into the boat. At 6 knots speed, the air changes shall be minimum 10 litre per person per minute in calm weather conditions. Ventilation openings shall be automatically closed in case of capsizing. Minimum one ventilation valve shall be fitted in the forward part of the boat. Minimum one ventilation valve shall be fitted in the aft part of the boat Propulsion An installation to prevent air formation in the fuel system in case of capsize shall be arranged. The ventilation arrangement for the fuel tank shall be such as to prevent the fuel from flowing out and water from entering the tank in case of capsizing Lifeboats with self-contained air support system Capacity The air system shall have a capacity of at least 10 minutes supply for the total number of people and engine, when the following conditions are accomplished: 1) The engine shall run with maximum load on propeller, pumps, generators etc. 2) The overpressure inside the boat shall remain between 5 and 20 mbar. 3) For calculation of air capacity a maximum pressure in the bottles of 18 MPa (180 bar) shall be assumed and the bottles shall be regarded as empty at 1.2 MPa (12 bar). 4) The working pressure of the air bottles shall be maximum 20 MPa (200 bar). The capacity shall be calculated based on minimum air consumption as 10 litres per minute per person Arrangement Bottles shall be arranged so that it is possible to assess their condition. The bottle pressure and the reduced air pressure shall be readable from the helmsman s position. It shall also be possible to read the pressure on the bottles individually without manipulation of the piping system. From the helmsman s position it shall be possible to read and adjust the pressure in the atmosphere inside the boat in relation to the outside pressure. The pipe system shall be so arranged that the bottles can be refilled without being removed from the boat. At least 2 air nozzles shall be arranged as far forward and aft, respectively, as possible in the boat. The nozzles shall have screens. The air system in the boat shall be capable to operate at any angle of heel up to 180 degrees to each side. The superstructure of the boat shall be fitted with an overpressure valve, which shall open at an overpressure of maximum 20 mbar. The superstructure of the boat shall be fitted with an underpressure valve, which shall open at an underpressure of maximum 20 mbar Components Any pipe installed shall be tested to a pressure at least 5 times the working pressure.

13 Standard for Certification - No Air bottles The air bottles shall be approved by a national authority and be marked in accordance with the standard applied by the approval of the bottles Fire-protected lifeboats Water spray system The water spray system shall be permanently installed and shall be capable of working effectively for at least 8 minutes and shall cover all the areas of the superstructure and hull above the waterline. The suction of the water spray system shall be positioned as low as possible in the boat. Start and stop of the water pump shall be an easy operation by 1 person near the helmsman s position. The pipe system should be arranged inside the boat in such way that only the nozzles are placed outside the boat. Pipes to the nozzles arranged outside the boat can be accepted if the free distance to the superstructure is less than 100 mm. The pipes shall be of corrosion resistant material. Inside flexible hoses may be accepted, if it can be shown that the heat conduction through a nozzle and its connection cannot damage the hose or stop the water spray function. The system shall be easy to operate, and shall be so installed that periodical testing can be undertaken when the boat is afloat as well as out of the water. The water pump shall not suffer damage, when the system is used without water Free-fall lifeboat Arrangement Except when the free-fall functions require special arrangements, outer and inner arrangement and equipment shall be as for totally enclosed lifeboats. The release of free-fall launching, start of engine and manoeuvre shall be activated from a position with good view inside the boat and adequate sight externally both forward, astern and to both sides. If the lifeboat shall be entered in sloping position, all the floor plates shall have non-skid surface, or arranged with steps to make the boarding easy. If necessary, the entrance to the seats shall be arranged with handles and hand rails. To ensure adequate lighting in order for the occupants to be seated and fasten the seat belt properly, the inner side of the boat shall be well-illuminated, and be so arranged that light always is switched on when the boat is in the davit. All portable equipment shall be safely secured against the maximum loads which can occur during free-fall launching Construction and strength The lowering and free fall hook arrangement, towing-cleats etc. shall be tested to the same criteria as for lifeboats in general. The strength of the hull and superstructure, windows, hatches etc. shall be designed with a safety factor of 6 against the free fall certification height load. Calculations on the hull verifying stresses of maximum 1/6 of the material strength shall be carried out by the manufacturer and submitted for information. Hull strength of free-fall lifeboats will be verified based on free-fall impact testing only Seat arrangement For optimum distribution of the load the seat back shall have a curvature with a radius of approximately mm except for the lowest 50 cm of the seat back which shall be straight. A support of the feet shall give an angle between the thighs and the back of between 80 degrees and 100 degrees. The seat shall give good support for a person s seat and thighs in this position. The neck part of the seat shall give side support for the head. The backrest part of the seat shall be located towards the forward end of the boat. The design of the seats shall be as shown in Fig Figure 11-1 Seat design The seats shall be fitted with padding, distributing the weight of the body over the whole part of head-, back and seat. The padding shall have a thickness of between 25 and 50 mm. The compression of the padding shall not be more than 15 mm when loaded with an evenly distributed pressure of 1.5 kp/cm 2. The surface of the padding material shall be easy to clean, be watertight and have good mechanical strength. To each seat there shall be a restraint harness to prevent vertical, longitudinal and transverse movement of the person. The colour of the harness shall contrast the colour of the padding. There shall be a simple regulation system to make the harness fit properly for persons of all sizes with survival suits on. If a head strap is used, the head strap may be made of a flexible material keeping the head firmly against the padding Rescue boats General Fender or buoyancy arrangement should be approved according to relevant ISO-standard Arrangement A stretcher area of 2.0 x 0.5 m shall be required, suitably for a person lying flat. Seaway in respect of having sufficient mobility and manoeuvrability as described by LSA Code is wind force 7 and open sea. A totally enclosed lifeboat may be approved as rescue boat, when all requirements in 1300 and LSA Code Ch. 5 are complied with. The boat shall have a deck where at least 2 persons can work and retrieve persons from the water, and bring persons on stretchers into the boat. The freeboard to this deck shall make it possible for 2 persons taking a person under his arms, when lying in the water, simulating a condition of full exhaustion, and not wearing an immersion suit or life jacket.
